Definitions

  • the nominal position of the vessel is maintained by so-called single point mooring systems, which allow the vessel to weathervane to take up a natural heading which offers the least resistance to wind, wave and current.
  • the depth of water beneath the keel of the vessel is sufficient to allow a sufficiently slack flexible hose system to be fitted. Consequently, the hose system can follow all the vessels movements and displacements as afforded by the single point mooring system, by simply adjusting its configuration.
  • the present invention provides apparatus for transferring fluid between a point on the seabed and a floating vessel, comprising a first flexible tube providing a fluid conduit and having a first end attachable to a floating vessel and a second end; a second flexible tube providing a fluid conduit and having a first end attached to a point on the seabed and a second end attachable for fluid communication with the first tube; and a structure mounted on the seabed having a movable member mounted thereon to which the second ends of the first and second tubes are attached, the movable member beings displaceable relative to the seabed structure in response to load on the first tube exceeding a predetermined threshold.
  • the apparatus therefore provides additional displacement capability which prevents the first hose from becoming stretched beyond its design limit.
  • the movable member consists of an arm with a first end pivotally mounted to the seabed structure for rotation about the structure and a second end to which the second ends of the first and second tubes are attached.
  • the movable member consists of a body mounted to the seabed structure for linear movement relative thereto.
  • the seabed structure may define a guide track in which the body is slidably mounted.
  • the first end of the second hose may be attached to the seabed structure which carries the movable member or may be attached to a point on the seabed displaced from the seabed structure.
  • this shows a conventional system whereby a floating vessel 1 is anchored to the seabed 3 by a chain or chain/wire combination 2.
  • a flexible hose system 4 connects the vessel with a given point 5 on the seabed, such as a wellhead.
  • FIG. 2 shows the same arrangement but now the vessel has been displaced by an amount X due to the action of wind, wave and current.
  • the flexible hose system 4 has sufficient length and flexibility to accommodate this displacement by adjusting its shape.
  • Figure 3 shows a conventional system used in shallower water, for example where the depth is about 30% of that in Figures 1 and 2.
  • the hose system 4 is too short to fully accommodate the displacement of the vessel.
  • the hose 4 becomes stretched beyond its design limit and can no longer operate and convey fluid safely.
  • FIG. 4 shows a first embodiment in accordance with the present invention which provides a solution to this problem.
  • a seabed structure 6 which carries a movable member 7.
  • the movable member 7 consists of an arm pivotally mounted to the seabed structure for rotation about the structure as indicated by the arrows in a substantially horizontal or slightly inclined plane.
  • the lower end of the flexible hose system 4 which was previously connected to a point on the seabed 5, is now connected to the end of the arm 7 remote from the seabed structure 6.
  • a second flexible hose 8 is provided, with one end attached to the end of the arm 7 so as to be in fluid communication with the first hose 4 and the other end attached to the wellhead 5.
  • the seabed structure 6 which carries the movable arm 7 is coincident with the wellhead 5 to which the second hose 8 is connected.
  • the wellhead 5 may be at a location spaced from the seabed structure 6.
  • the vessel 1 In operation, if the vessel 1 is displaced and therefore stretches out the first hose 4, once the load imposed on the hose 4 exceeds a given point, it will cause the movable arm 7 will rotate so as to accommodate the stretching of the hose 4 and allow it to resume a more normal configuration. Thus, the free end of the arm 7 will rotate such that the tangent to its arc rotation is directed approximately in the same direction as the vessel displacement.
  • the movable member 7 consists of a body mounted for linear movement on a seabed structure 6.
  • the seabed structure 6 may define a guide track along which the movable body can slide.
  • two flexible hoses 4 and B are required which are attached in fluid communication with each other at the movable meter 7.
  • the other end of the second flexible hose 8 is attached to the wellhead 5 at a location displaced from the seabed structure 6.
  • seabed structure and movable meter can be altered as desired to provide rotational or linear movement or a combination of the two in any appropriate form which will allow the lower end of the hose 4 to be displaced relative to the wellhead on the seabed without becoming stretched beyond its design limit.
